Description

"Vorrichtung zur Höhenverstellung von Sitzen, insbesondere raftfahrzeugsitzen" Die Erfindung betrifft eine Vorrichtung zur Höhenverstellung von Sitzen, insbesondere Kraftfahrzeugsitzen mit einem festen Unterrahmen, der über vorzugsweise gelenkig mit diesem verbundene Lenker abgestützt ist."Device for height adjustment of seats, especially raft vehicle seats" The invention relates to a device for adjusting the height of seats, in particular Motor vehicle seats with a fixed subframe, which is preferably articulated is supported with this connected handlebar.

Bekannte Höhenverstelleinrichtungen haben den Nachteil, daß vertikale Sitzbewegungen.von vergleichbar gronen horizontalen Bewegungen begleitet werden, die durch eine nachträgliche Längsverstellung des Sitzes wieder korrigiert werden müssen.Known height adjustment devices have the disadvantage that vertical Sitting movements are accompanied by comparatively large horizontal movements, which can be corrected by later adjusting the seat lengthways have to.

Bei anderen bekannten Höhenverstelleinrichtungen andere sich während des Verstelivorganges die Neigung des Sitzkissens in nachteiliger Weise.In other known height adjustment devices other during of the adjustment process adversely affects the inclination of the seat cushion.

Es ist Aufgabe der Erfindung, eine )iöhenverstelleinricIltung zu schaffen, mittels der ein großer vertikaler Verstollweg ohne größere horizontale Verstellung erreicht werden kann.It is the object of the invention to create a height adjustment device by means of which a large vertical locking path without major horizontal adjustment can be reached.

Gleichzeitig soll die gewählte Neigung des Sitzkissens im Zuge des Verstellvorganscs weitestgehend beibehalten werden.At the same time, the selected inclination of the seat cushion in the course of the Verstellvorganscs are largely retained.

Schließlich soll die Verstelleinrichtung eine geringe Bauhöhe aufweisen, um den Sitz auch in Sportfahrzcuge einbauen zu können.Finally, the adjustment device should have a low overall height, so that the seat can also be installed in sports vehicles.

Deshalb wird eine Vorrichtung zur Höhenverstellung von Sitzen insbesondere Kraftf<ihrzeugsitzen mit einem festen Unterrajuien, der über vorzugsweise gelartig mit diese. verbundene Lenker abgestützt ist, vorgeschlagen, wobei erfindugsgemäß die oberen Enden der Lenker jeweils von den Endbereichen der durch Führungsschienen oder Konsolen gebildeten Längsseiten des Unterrahmens aufsenonimen werden, wobei jeder vordere Lenker mit dem Unterraiu:ien einen stumpfen Winliel einschließend mit einem fahrzeugbodenfesten Teil verbunden ist, und wobei jeder hintere Lenker mit einem schwenkbar am Fahrzeugboden angelenkten Hebel in Verbindung steht, dessen Schwenkbewegung durch ein an sich bekanntes Verstellorgan ausgelöst wird.Therefore, a device for adjusting the height of seats in particular Powerful seats with a firm lower surface that is preferably gel-like with this. connected handlebars is supported, proposed, wherein according to the invention, the upper ends of the handlebars each from the end regions of the through Guide rails or consoles formed on the long sides of the subframe on senonimen each front handlebar with the Unterraiu: ien a blunt winliel including is connected to a part fixed to the vehicle floor, and each rear handlebars in connection with a pivotable lever articulated on the vehicle floor stands, the pivoting movement triggered by an adjusting member known per se will.

Bei einem bevorzugten Ausführungsbeispiel der Erfindung wird vom oberen Anlenkpunkt jedes vorderen Lenkers eine Strebe aufgenommen, die ihrerseits mit dem Hebel gelenkig verbunden ist. Durch diese Anordnung wird eine besonders günstige Einleitung der Verstellkräfte erreicht.In a preferred embodiment of the invention, from the above Articulation point of each front link added a strut, which in turn with the Lever is articulated. This arrangement makes a particularly favorable one Introduction of the adjustment forces achieved.

Es wäre auch möglich, pro Sitz nur eine Strebe und diese vor-¢,sgsweise in Sitzmitte verlaufend anzuordnen, oder aber jeweils zwei, ein starres Kreuz bildende Streben vorzusehen, wodurch eine Erhöllung { } Querstabilität eintritt.It would also be possible to have only one strut per seat and this for example to be arranged running in the middle of the seat, or two at a time, forming a rigid cross To provide struts, whereby an increase {} transverse stability occurs.

Eine den individuellen Wünschen angepaßte Neigung des Sitzkissens kann erreicht werden, wenn die wirksame Länge der Streben veränderlich ist.An inclination of the seat cushion adapted to the individual wishes can be achieved if the effective length of the struts is variable.

Zur besseren Abstützung des Sitzes ist es zweckmäßig1 wenn das fahrzeugfeste Teil jeweils von einer Lasche gebildet wird, die von einem Fahrzeugquerträger abragt.For better support of the seat it is advisable1 if the vehicle is fixed Part is each formed by a tab that protrudes from a vehicle cross member.

Bei einem vorteilhaften Ausführungsbeispiel der Erfindung kann der Hebel jeweils als Winkelhebel ausgebildet sein, dessen einer Schenkel neben der Strebe auch das sich am Fahrzeug querträger abstützende Verstellorgan aufninunt.In an advantageous embodiment of the invention, the Lever each be designed as an angle lever, one leg of which next to the Strive also to pick up the adjusting member supported on the vehicle cross member.

Bei einem weiteren vorteilhaften Ausführungsbeispiel der Erfindung kann der hebel jeweils als Wippe ausgebildet sein, deren eine Seite den hinteren Lenker, deren nach oben mit einem Fortsatz versehener Mittelteil die Strebe und deren andere Seite das sich an der Längsseite des Unterrahmens abstützende Verstellorgan aufnimmt.In a further advantageous embodiment of the invention can the lever can be designed as a rocker, one side of which is the rear handlebar, whose middle part provided with an extension at the top is the strut and the other Page receives the adjusting member supported on the longitudinal side of the lower frame.

Bei den vorgenannten Ausführungsbeispielen stützt sich das Verstellorgan, das z.B. hydraulisch, elektrisch oder mechanisch angetrieben sein kann, nicht direkt ain Fahrzeugboden ab, wodurch der Einbau der Sitzanlage vereinfacht wird.In the aforementioned exemplary embodiments, the adjusting element is supported which can be driven hydraulically, electrically or mechanically, for example, not directly ain the vehicle floor, which simplifies the installation of the seating system.

Wesentliche Vorteile ergeben sich, wenn die vorderen Lenker als Biegefedern ausgebildet werden, die das Bestreben haben, den Sitz anzuheben. Dadurch können zusätzlich Entlastungsfedern und auch Gelenke eingespart werden. Gleichzeitig wird einer möglichen Klapperneigung des Sitzes entgegengewirkt und eine Entlastung der Streben erreicht.There are significant advantages when the front links are used as spiral springs be trained who strive to raise the seat. This allows In addition, relief springs and joints can be saved. At the same time will a possible tendency of the seat to rattle counteracted and a relief of the Aspiration achieved.

Eine weitere GerBus cluuinderung wird geschaffen, wenn die Gelenkstelle der Lenker und der Streben als z.B. aus Gumstimetallelementen bestehende elastische Lager ausgebildet sind. Neben der Wartungsfreiheit der Gelenkstellen wird auch noch eine gedämpfte Aufhängung des Sitzes erreicht.Another GerBus cluster is created when the joint site the handlebars and the struts as elastic ones consisting, for example, of rubber-metal elements Bearings are formed. In addition to the maintenance-free articulation, there is also a dampened suspension of the seat is achieved.

Zur Minderung der Verletzungsgefahr bei Unfällen ist es zweckmäßig, wenn die Verstellorgane beim Uberschreiten einer vorgegebenen Belastung ihre wirksame Länge unter Energieabsorption verändern.To reduce the risk of injury in the event of an accident, it is advisable to if the adjusting elements are effective when a given load is exceeded Change length while absorbing energy.

Der Gegenstand der Erfindung soll nachfolgend anhand von zwei in der beiliegenden Zeichnung dargestellten Ausführungsbeispielen näher erläutert werden. In der Zeichnung zeigen Fig. 1 einen erfindungsgemäß ausgerüsteten Fahrzeugsitz mit einem als Wippe ausgebildeten Schwenkhebel und Fig. 2 ein weiteres Ausführungsbeispiel, bei dem der Schwenkhebel einen Winkelhebel darstellt.The object of the invention will be based on two in the Embodiments illustrated in the accompanying drawing are explained in more detail. In the drawing, FIG. 1 shows a vehicle seat equipped according to the invention with a swivel lever designed as a rocker and Fig. 2 is another Embodiment in which the pivot lever is an angle lever.

Ein Sitz 1, dessen fester Unterrahmen 2 im wesentlichen aus in Fahrzeuglängsrichtung verlaufenden Führungsschienen 3 gebildet wird, stützt sich über paarweise angeordnete vordere Lenker 4 und hintere Lenker 5 ab. Die oberen Sonden der Lenker 4 und 5 werden jeweils von den Endbereichen der FUhrungsschienen 3 aufgenommen. Während jeder vordere Lenker 4 mit einer von einem Fahrzeugquerträger 6 abragenden Lasche 7 - wobei diese ein fahrzeugbodenfestes Teil 8 bildet - gelenkig verbunden ist, sind die beiden hinteren Lenker 5 an einen Hebel 9 angelenkt.A seat 1, the fixed lower frame 2 of which essentially extends in the longitudinal direction of the vehicle extending guide rails 3 is formed, is based on pairs arranged front handlebar 4 and rear handlebar 5. The upper probes of handlebars 4 and 5 become each recorded by the end regions of the guide rails 3. During each front Handlebar 4 with a tab 7 protruding from a vehicle cross member 6 - this being the case forms a part 8 fixed to the vehicle floor - is articulated, the two are rear link 5 articulated to a lever 9.

Wie aus Fig. 1 ersichtlich, ist der Hebel 9 als Wippe 10 ausgebildet, die schwenkbar mit dem Fahrzeugboden 11 in Verbindung steht. Dabei nimmt eine Seite jeder Wippe 10 den hinteren Lenker 5, ein nach oben von der Wippe 10 abragender Fortsatz 12 eine zu. oberen Anlenkpunkt des vorderen Lenkers 4 führende Strebe 13 und die andere Seite der Wippe 10 ein sich an der unteren Führungsschiene 3 abstützendes Verstellorgan i4 auf. Dieses Veretsllorgan 14 kann sowohl durch Hilfskraft beaufschlagbar als'auCh elektrisch oder mechanisch betätigbar sein. Wird die Wippe 10 durch den Einfluß des Verstellorganes 14 gekippt, so bewegen sich die Anlenkstellen der hinteren Lenker 5 und der Streben 13 auf reisbahnen unterschiedlicher Durchmesser - wobei der Bahnradius der Streben 13 kleiner ist als der der hinteren Lenker 5 - und führen den Sitz 1 bis in die strichpunktiert angedeutete Endlage.As can be seen from Fig. 1, the lever 9 is designed as a rocker 10, which is pivotably connected to the vehicle floor 11. Doing so takes one side Each rocker 10 has the rear link 5, one that protrudes upward from the rocker 10 Appendix 12 one to. upper pivot point of the front link 4 leading strut 13 and the other side of the rocker 10 is supported on the lower guide rail 3 Adjusting i4 on. This Veretsllorgan 14 can be acted upon by auxiliary power can also be operated electrically or mechanically. If the rocker 10 by the Influence of the adjusting member 14 tilted, so move the articulation points of the rear Handlebars 5 and the struts 13 on travel paths of different diameters - with the radius of the path of the struts 13 is smaller than that of the rear link 5 - and lead the seat 1 up to the end position indicated by dash-dotted lines.

Das in Fig. 2 dargestellte Ausführungsbeispiel der Erfindung unterscheidet sich nur geringfügig von dem in Fig. 1 wiedergegebenen. Unterschiedlich hierzu ist jeder Hebel 9 als Winkelhebel 15 ausgebildet, dessen einer Schenkel 16 den hinteren Lenker 5 und dessen anderer Schenkel 17 neben der Strebe 13, deren wirksame Länge zur Änderung der Sitzkissenneigung verändert werden kann, auch das sich am Fahrzeugquerträger 6 abstützende Verstellorgan 14 aufnimmt.The embodiment of the invention shown in Fig. 2 differs differs only slightly from that shown in FIG. This is different from this each lever 9 designed as an angle lever 15, one leg 16 of which is the rear Handlebars 5 and its other leg 17 in addition to the strut 13, the effective length of which can be changed the seat cushion inclination can be changed, including that on the vehicle cross member 6 supporting adjusting member 14 receives.
